What does AI visibility mean?
It is how likely a large language model is to recognize your brand, describe it accurately, and mention it in response to category-level questions. As AI-powered answers (ChatGPT, Perplexity, Google AI Overviews) become mainstream, this is becoming a meaningful source of discovery traffic - and invisibility in LLMs means invisibility in that channel.
How does this tool check visibility?
It queries a GPT-class model with carefully-structured prompts about your brand and the category you operate in, then parses the response into four parts: direct recognition (does the model know you?), descriptive accuracy, category mention likelihood, and competitive context. The output is grounded in the model's actual training data - there is no invention.
Which AI model does this test against?
The current tool uses OpenAI's GPT-5 nano as a single representative model. Because all major frontier LLMs train on broadly similar web corpora, recognition by one model is a strong proxy for recognition by others. For brand-critical assessments, cross-check with Claude, Gemini, and Perplexity directly.
What if the tool says my brand is 'unknown'?
It means the model has no reliable information about your brand in its training data. This usually means one of three things: you are new, you have low presence on authoritative sites (Wikipedia, major publications, large forums), or your brand name is generic enough to get confused with other terms. The recommendations list will suggest specific channels to build that presence.
Will AI visibility affect my Google rankings?
Indirectly, yes. The same signals that make a brand AI-visible - Wikipedia presence, authoritative backlinks, consistent schema markup, a clear topical identity - also strengthen traditional SEO. Investing in AI visibility is not a separate discipline; it is entity-first SEO done right.
Is this tool free?
Yes. 1 check uses 1 of your 5 daily AI generations (shared across all RankPill AI tools). Identical brand + category queries are cached for 24 hours and do not consume your quota.
